curved pipe H, leading from the outer side of; thesaid cock into thesaid recess i,'communicatestherewith by means of the outwardly openingvalve 70. By turning the key of the four way cock, one of the pipes E,can be thrown into direct communication with the pipe F, and the otherpipe E, into direct communication with the pipe H, and vice versa; whichcauses one of the compartments of the water chamber A, to be connectedto theengine cylinder B, by means of anlinwardly opening valve, and theother by an outwardly opening valve, as shown in Fig. 4. Therebyenabling air to be drawn from oneof the compartments of the chamber A,and forced into the other, and vice versa. The key of the four way cockis connected to the beam J, which operates the piston s, of the pumpingengine, in such a manner thatthe' saidv key will be automati- :callyoperated after a certain number of strokes of the said piston; viz: thelever (1,,

which is connected to the key of the said fourway cock, is attached to asliding plate 6," which has a cam shaped aperture in it :and is movedback and forth at intervals by a pin h, on the ratchet wheel h, as thesaid [ratchet wheel ismade to revolve bymeans ofia click pin '5', on thereciprocating pawl bar I the said bar being reciprocated back and forthin consequence of its being joint ed to the lever n, which 'is connectedto the operating beam J. l

1 The pin Won the ratchet wheel h,-it will be perceived, works in thecam shaped aperature in the plate 6, thereby causing each revolution ofsaid wheel to move the plate e, once back and forth. Consequently, itwill be perceived that by varying the size of the said ratchet wheel, orthe number of teeth upon it, the movements of the key of the four waycock may bear any proportion to the strokes of the engine piston thatmay be desired. The said sliding plate 6, is sustained by the guidingplates f. i

The lower end of the cylinder B, of the pumping engine, is formed withan open mouthed tapering concentric tube a, rising from its upper side.in which the piston rod 4", plays. The piston s, has a tapering tubuflarconcentric projection Q), rising from its upper surface, which is ofsuch asize and shape as to allow the annular portion of the piston todescend to the annular portion of the lower cylinder head without comingin contact with the tubular projection a, which rises therefrom. Thepiston rod r, is connected to the top of the elevated central portion0), of the piston, and inwardly opening valves to, w, cover apertures inthe top of 22, through which air is admitted into the cylinder above thepiston.

To insure a proper supply of oil above the piston s, I make an openingin the annular portion thereof and cover it by the inwardly openingvalve t. As soon as the oil that has been introduced above the piston,has found its way to the bottom of the cylinder, it will be perceivedthat it will be at once forced up above the cylinder again through theaperture covered by the valve 2?.

The operation of my water elevating apparatus is as follows, viz: At thestart, both compartments of the water chamber A, are filled with water.The reciprocating movements of the piston of the engine, will force airthrough the aperture, covered by the valve is, into the pipe H, which,by means of the four way cock, will be conducted into one of the pipesE, and by that into one of the compartments of the water chamber.

The air will be forced into said chamber until concentrated to such adegree that the water will be forced therefrom through the educationpipe D. At about the time that the water is all expelled from saidcompartment, the movements of the ratchet wheel h,

acting upon the sliding plate 2, will change the position of the key ofthe four way cock, and thereby bring the full water compartment intoconnection with the air engine cylinder through the medium of the pipeE, and the curved pipe H, and the emptied water compartment intoconnection with said cylinder through the medium of the air pipe E, andthe short pipe F, which will allow the compressed air in the said emptywater chamber to rush into the cylinder of the engine, and supply theengine with the air necessary to force the water out of the othercompartment of the water chamber. As soon as a sufficient quantity ofair has been discharged from the emptied compartment of the waterchamber to reduce its pressure below the degree of pressure of the wateron the outer side of its valve g, the said valve will open and allow thesaid compartment to again fill with water. And thus the operation may becontinued automatically as long as may be desired. The very greatadvantage produced by supplying the air engine with compressed air fromthe compartment of the water chamber from which the water has just beenexpelled, for the purpose of being used in expelling the Water from theother compartment of the water chamher, will readily be appreciated byevery one familiar with the subject. Water is forced from the waterchamber A, through the pipe I), which communicates with bothcompartments of said chamber by means of the oifset c, and the tubes 6,b, descending from said offset on either side of the partition a, nearlyto the bottom of the compartments A, and A, as shown in Fig. 6.

What I claim as my invention and desire to secure by Letters Patent, is-

The transference of the lubricating oil from the bot-tom of the enginecylinder to the upper side of the piston thereof, for the purpose ofinsuring the proper lubrication of said piston, substantially as hereinset forth.

The above specification of my new and useful improvement in air pumpsfor raising water signed and witnessed this 27th day of December, 1854.
